Our first thought was the master cylinder connecter shorted because some brake fluid might have spilled (not leaked) during replacement. The dealer when through all the steps, even changing out all the parts in my car with another M3 and that didn't do anything. It was determined that the DME went bad so they took out the ECU, sent that to germany, and gave me a fresh one. Problem was solved.
Gotcha, sounds like the dealer got a bit more money from BMW for the ECU replacement.
